constructed according to my invention. Fig.. 2 is a transverse section of the same. Fig. 3

My invention relates to improvements in drain-tile-perforating machines and drain-tiles produced thereby; and the objects of my improvements are to produce a simple and inexpensive perforating-machine having the plates carrying the perforating-pins adjustable vertically and horizontally7 and adapted to be used in connection with a drainftilemolding inachinc producing various sizes of pipes.

Heretofore drain`pipes have been provided with perforationson one side thereof', (to be the upside when laid in trenches,) or even upon-their sides by retaining solid the side intended to rest upon the ground. Drain-pipes provided with a coupling-collar or enlargement at one end to receive the small end of a correspondingly-formed tile have been provided in their narrow portions with perforations formed at an acute angle to the axis of the tile; but they do not present all the advantages oblrained by my construction, whichrelates to a cylindrical tile of uniform diameter through out its length, provided with tine perforations uniformly arranged all around said tile,which permits it to dry more quickly and uniformly and to beburned more evenly. I attain these objects by the construction shown in the drawings, in` which- A represents a platform. mounted upon legs A and A2, and upon this platform are placed two sets of transversely-slidin g ways,B and B',

retained sidewise by guides C, secured to the top of the platform. The ways Bproject on one side of the platform andthe waysB' 011 the opposite side, and to thcseproj ecting ends are'pivoted at Z1 one end -of `bell-crank levers These levers are pivotedtol thelegs A at b2, andthe opposite lend of eachbell-crank is pivoted at '1is to the upper endof a vertical connecting-rod, E, that is secured at bt to one end of a long hat spring, F, having its opposite end secured at f to the Vunder side of the platform A,adj oining the legs A2. The object of this springis to normally keepthe end D of the bell-cranks elevated, (in position to be depressed by the operators foot,) and cause the outerend of the ways B B' to project over the edges of` the platform. These ways `carry secured to their upper surface vertical brachets b5, to the upper portion of which is attached, by means of screws b, passing adjustably through a slot in each bracket, a plate, G, having a series of pins, g, arranged in rows and projecting toward the center of the machine. The plates G, thus connected with the Ways B and B', are forced toward each other by means of a treadle, II, having its inner end pivoted to one of the legs, A', at a, and its middle por- `tion connected at hto the connecting-rod E uniting the bell-cranks D. Upon one end of the platform a vertical bracket, A, is secured centrally, and carries a tube, I, of slightly smaller diameter externally than the interior diameter of the tile K that is to be perforated. One end of this tube I is left unsupported to readily receive the tile K endwise thereon, and` is provided with perforations t', to receive the ends of the perforating-pins g.. Vithin the tube or cylinder I and bracket A3 is placed loosely the cylinder-cleaner L, formed of three or four parallel wires, Z, united at one end to a conical point, Z', and at the other to a handle, l, by means of which it can be rotated to pulverize and remove any particles of clay that are forced from thc tile into the cylinder I by the pins g. 4

Slightly above the platform A there is secured thereto a track or rail, A*, upon which is mounted a carriage, M, having its upper face concave to receive the tile K from a suitable tile-press or molding-machine and convey it to thepipc or cylinder I, in position to be perforated, and from said cylinder back to a position from which it can be removed from IOO the machine after it has `been perforated, as shown at k. W'hile'the tile is upon the cylinder I, it first. receives fine perforations upon two sides by theV attendant pressing upon the treadle H and forcing,` the pins g into the still soft clay of the tile. Said tile is then Vrevolved a quarter of a circle, and the remaining,` sides are similarly perforated.

Having thus fully described my invention, I claim- 1. In a tile-perforating` machine, the combination of a platform, A, AWays B and B, having plates G and pins g, adapted to move to- Ward eachother, and perforated tile I between said pins, substantially as and 'for the purpose described. Y

2; rlhe combination of platform A, ways B and B', and plates G,provided with pins g,\vith bell-cranks D, treadle H, and connecting-rod E, substantially asy and for the purpose set forth.`

3. The combination of a platform, A, Ways B and B', plates G,and pins g with bell-cranks, a treadle,connecting-rod, and spring, substantially as and for the purpose described. y

4. In a tile-perforating machine, the combination of laterally-movable plates G, carrying-pins g,with tube I, having perforations rin the sides thereof, and tube-cleaner Ii, having a conical point, Z,-at one end, a handle at the other, and aseries of parallel Wires between them, substantially as and for the purpose described. p

5. VAs a new article of manufacture, a cylindrical tile of uniform diameter from one end to the other, and provided with fine perforations upon the Whole periphery thereof, substalr tially as and for the purpose described.

In testimony whereof I affix my signature in presence of two Witnesses. v HIBAM l?. STAFFORD.
